 - Use panel border tokens instead of one-off `border-white/10` and `bg-black/20` combinations when the surface belongs to the notch-clipped chrome language.
 - Use the four-step surface ramp to create visible lift. Do not introduce intermediate dark greens for local component depth.
 - Use `--color-ops-accent-deep` for structural rails, hero tail tracks, section ticks, and today rails that should recede behind live readiness status.
+- Use `--ops-rail-baseline` for quiet structural emerald lines that need to align across telemetry, section ticks, history momentum, and footer separation.

 - Use uniform calm `SignalCard` chrome for backup summary signals. Express caution with the left spine or an inline tone chip rather than recoloring the entire card amber when the state is an intended safety lock.
 - Accordion status chips stay in `.ops-export-accordion-status` so badge alignment remains stable across open and collapsed recovery panels.

 - `.ops-section-emphasis-standard` is the default shell weight for read-only mirrors such as history.
 - `.ops-section-emphasis-support` drops the emerald outer wash and uses structural framing for support or recovery surfaces.
 - Apply these through `SectionCard` only. They recalibrate shell hierarchy without changing notch geometry, focus chrome, or component signatures downstream.
